Texting before a date?

today is the day before the date and I was wondering if I should text her anything tonight to start a convo and just talk? Or should I do that tomorrow during the day before the date? I do want to talk to her just to confirm the time and let her know I'm looking forward to the date.

so when do you think I should text her?

and do you guys have any suggestions for texting conversation starters that aren't just "hey" or "what up?". I suck at texting...
